Ability to use byte arrays, InputStream and OutputStream

[Monniasza]

I'd like to use InputStream for use in my game because it uses MP3 files stored in ZIP archives.
I also use byte arrays to buffer ZIP file data for class loading and recognition from InputStreams

This would require:

• removal of FileWrapper class
• adding extra constructors for InputStream and byte[]
• adding extra write functions for OutputStream and byte[]
